Title: Production of ceramic green sheet
Inventor: KINUGASA MASANORI
IPC: B28B1/30
Filed: 1987-03-25
Abstract: PURPOSE:To enable a uniform ceramic sheet free of pinholes to be easily formed, by placing electrode plates in a ceramic-containing liquid, and passing an electric current between the electrode plates. CONSTITUTION:A ceramic powder is a powder of a dielectric, for example, barium titanate. The average particle diameter of the powder used is preferably not more than 0.5mum, and is preferably not more than 1/20 times the thickness of an objective sheet. As a binder is used an ionic higher molecular weight resin, for example a resin obtained by neutralizing amino groups of a polyamino resin with a carboxylic acid or a resin obtained by neutralizing a polycarboxylic acid resin with a base (e.g., ammonia or amine). The binder adheres to the ceramic powder, thereby assisting the ceramic powder in moving to an electrode. A solvent to be used may be any one which dissolves the binder or the like and in which the powder such as the ceramic powder can be dispersed, for example, water, an organic solvent or mixture thereof.

Title: Circuit device for forming frequency signal
Inventor: SCHMIDT DIERK
IPC: G01S7/4911
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To enable generation of various frequencies with high accuracy with a simple means by deriving a pair of frequencies with tightly adjacent frequencies from a frequency oscillator. SOLUTION: As a reference signal 16', an optical switch 22 transmits a transmission signal 16 reflected at an object 18. A frequency divider 28 performs frequency division on a frequency f0 , generated by a quartz oscillator 52 into frequencies f10 to f30 to become amplifying signals of frequencies f1 -f3 via a filter 30 and an amplifier 32. In addition, a switched frequency divider 34 performs frequency division on the frequency f0 into frequencies f'10 to f'30 to become the amplifying signals of frequencies f'1 -f'3 via a filter 36 and an amplifier 38, and an optical transmitter 12 receives the input of the signals f'1 -f'3 for modulating the transmission signal 16.  Then sequentially continuous electrical signals are impressed on an optical receiver 14 and converts them into an evaluation signal 42, including each of the phase angles of an object signal 20 and the reference signal 16' by mixing. By forming two phase angle differences for each measured frequency, reference amount falls out, a phase angle is obtained for each measured frequency pair f'1 -f1 to f'3 -f3 , and a pair from among them having the minimum frequency in the univocal region of distance measurement is determined.

Inventor: FUKAZAWA OSAMU
IPC: F02D43/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To enrich an air-fuel ratio favorably in responsiveness at the time of temporarily changing the air-fuel ratio over to rich while lean-driving a cylinder injection engine. SOLUTION: This control device restrain a change of an air system such as intake air quantity, swirl current strength, EGR quantity, etc., by fixing throttle opening, swirl control valve opening, EGR valve opening by a current control value or controlling them to the closing side only by fine quantity α0-α2. Thereafter, fuel injection quantity is increased by changing fuel injection timing from a compression process (stratified charge combustion) over to an air intake process (homogeneous combustion) where a corrective range of ignition timing is extensive. Consequently, an air-fuel ratio of air-fuel mixture speedily changes in accordance with a change of the fuel injection quantity, and the air-fuel ratio is enriched favorably in responsiveness for a demand for enrichment.  Additionally, at the time of changing it over to enrichment, it is possible to improve drivability by delaying the ignition timing and restraining a torque change in accordance with a change of the air-fuel ratio.

Title: Abrasives for pinball
Inventor: YOKOTA HISAO
IPC: B24B31/14
Filed: 1983-04-25
Abstract: PURPOSE:To prevent a plating layer on a pinball from damage to maintain gloss and prevent the pinball from deposit of abrasives due to an electrostatic phenomenon, by using pellet-like polyethylene containing a specified weight % of calcium carbonate for the abrasives. CONSTITUTION:Abrasives consist of polyethylene pellets containing 10-70, preferably 10-60wt% of carbonate. Since carystal of alkaline earth metal acid salt exposed to the surface layer of the pellet has a proper hardness, even persistent rust can be removed easily from the surface of pinball. Further, since this carbonate of chemically basic salt acts on stains, such as dirt from the hands, deposited to the surface of steel balls to promote the chemical decomposition, the stains can be effectively removed to maintain gloss. Also, by beforehand mixing antistatic material into the pellets can be prevented frictional electricity from charging and attachment and accumulation on insulating portions in a circulating system.

Title: Electrophotographic carrier
Inventor: TAKEDA MASAYUKI
IPC: G03G9/10
Filed: 1987-03-30
Abstract: PURPOSE:To obtain an electrophotographic carrier having a large capacity for electric charge causing no decrease of the charge in running stage of an electrophotographic device by using a resin having <=2 penetration and >=200kg/cm<2> tensile yield strength for the carrier. CONSTITUTION:The carrier of this invention is obtnd. by spray cooling a carrier material consisting of a resin and magnetic powder as essential components after melting the carrier material. A resin having <=2 penetration and >=200kg/cm<2> tensile yield strength is used for the resin in this case. Since the magnetic fine particles are scarcely isolated from the surface of the carrier material, the stability of the material against changes of environmental conditions, particularly the change of electric charge from summer season to winter season, is remarkably superior to a carrier comprising magnetic particles dispersed by kneading/crushing method. Moreover, since the particles of the carrier are close to spherical shape having a hardness and elasticity higher than each specified value, contamination of a background of a copy due to sticking of the carrier to a photosensitive body is inhibited.
